Indoor Heather (Erica) Care: A Challenge for Beginners

True heather (Calluna) requires cold winters and fails indoors. What's sold as "indoor heather" is usually Erica (heath), which demands all‑day direct sun from an unobstructed south window, cool temperatures, acidic porous soil (high peat), and careful watering—let the top dry slightly between drinks. Fertilize sparingly with half‑strength Miracid.

These conditions are hard to meet indoors; Erica is not recommended for inexperienced growers.
